High Power 1443.5 nm Laser with Nd:YAG Single Crystal Fiber

High Power 1443.5 nm Laser with Nd:YAG Single Crystal Fiber

A high-power eye-safe 1443.5 nm laser was demonstrated with an Nd:YAG single crystal fiber (SCF) as the gain medium. For continuous wave (CW) operation, a maximum output power of 13.3 W was obtained under an absorbed pump power of 95.0 W, corresponding to an optical-to-optical conversion efficiency...
